How to add a click event to <p> elements in iframe (using jQuery)
<iframe frameborder="0" id开发者_Python百科="oframe" src="iframe.html" width="100%" name="oframe">
There's a special jQuery function that does that: .contents(). See the example for how it's works.
Your best best bet is to invoke the iframe AS LONG AS it's part of your domain.
iframe.html
<html>
<head>
<script>
window.MyMethod = function()
{
$('p').click();
}
</script>
</head>
<body></body>
</html>
And then use
document.getElementById('targetFrame').contentWindow.MyMethod();
To invoke that function.
another way is to access the iframe via window.frames.
<iframe name="myIframe" src="iframe.html"/>
and the javascript
child_frame = window.frames['myIframe'].document;
$('p',child_frame).click(function(){
alert('This click as bound via the parent frame')
});
That should work fine.
Wanted to add this, as a complete, copy-paste solution (works on Firefox and Chrome). Sometimes it is easy to miss to remember to call the event after the document, and so the iframe, is fully loaded:
$('#iframe').on('load', function() {
$('#iframe').contents().find('#div-in-iframe').click(function() {
// ...
});
});
The iframe must be on the same domain for this to work.
By giving a reference to the IFrame document as the second parameter to jQuery, which is the context:
jQuery("p", document.frames["oframe"].document).click(...);
To access any element from within an iframe, a simple JavaScript approach is as follows:
var iframe = document.getElementById("iframe");
var iframeDoc = iframe.contentDocument || iframe.contentWindow;
// Get HTML element
var iframeHtml = iframeDoc.getElementsByTagName("html")[0];
Now you can select any element using this html element
iframeHtml.getElementById("someElement");
Now, you can bind any event you want to this element. Hope this helps. Sorry for incorrect English.
